The buttons to beattached are indicated by the reference character A, the wire from which the staples are formed is indicated by the letter B and the fabric to which the buttons are to be attached is indicated by the letter C.

as is shown in Fig. XIX.

cutting movement then takes place which is followed by the staple forming movement and the operation of the machine is con .cluded by the staple driving and clenching movement. However, although the button feeding movement is completed at the be-.

ginning of the down stroke of the-operating rod, nevertheless during the remainder of the stroke the button feed finger is actuated to lift the same and to return it to starting position. All of the parts are operated by the downward movement of the operating rod 29 which is actuated by the depression of the foot lever 21 in a manner which will be clear from an inspection of Fig. IV of the drawing.

\Ve will first consider the button feeding movement and the operation of the button feed finger. This movement is clearly shown in Figs. V and VI of the drawing. The full lines in Fig. V show the position of these parts at the beginning of the down stroke of the operating rod 29. The downward movement of the operating rod 29 causes the cam 33 which is connected to the upper end of said operating rod to rock upon the shaft 35. This cam 33 carries fixed theretothe arm 36 and as the cam 33 rocks the pin 38 on the end of the arm 36 rides in the curved slot 39.. This causes the arm 40 to swing forward on its pivot 11 thus actuating the button feed finger slide 42 through the pin and slot connection at the top of the arm 40. The button feed finger 45 is held in an elevated position against the tension of the spring 19 by the stop 85. As the arm -10 is swung on its pivot 11, moving the button feed finger slide 42 forward, the button feed finger is moved off the stop 85 allowing it to swing downward into engagement with a button As the button feed finger slide moves forward, the button is carried by the part 46 of the button feed finger 45 to a position adjacent the end of the staple forming slide 165 as appears in dotted lines in Fig. XXXIII. The dotted lines in Fig. V show the position of the parts at this stage of the operation. As the down stroke of the operating rod 29 is continued the nose 1-l-3 of the cam 33 engages the upper cam surface l-H of the cam 10.)

I and tilts it forwardupon its pivot 102 so shown in Fig. VI, the inclined surfaces of said slide moving 'on the inclined surfaces of the upper and lower cam blocks respectively, and thus lifting the upper cam block 55 against the tension of the spring 62 and lifting the button feed finger slide 42 which is carried by the upper cam block 55 so as to lift the button feed finger away from the buttonA which has been carried down to the end of the staple forming slide. This lifting of the button feed finger does not occur until after a wire has been put through the eye of the button so that it is held in place in the end of the staple forming slide. At the same time that the arm 83 is broughtforward to force forward the cam slide the arm 40 is swung backward on its pivot somewhat due to the shape of "the cam slot 39. This causes the button feed finger to move rearwardly a slight distance for a purpose which will be hereinafter described.

The full lines in Fig. VI show the position of the parts at the end of the down stroke of the operating rod. When the pressure is released from the foot lever 21 and the operating rod 29 moves upward under the influence of the spring 31 the arm 40 is swung rearwardly on its pivot 41 carrying with it the button feed finger slide 42. As this moves backward the shoulder v7 9 strikes the pin 77- moving it backward so as to give the cam slide a rearward impulse whereupon the spring 62 acting upon the upper cam block forces the cam slide rearwardly to the position shown in Fig. V, thus allowing the cam block 55 and button feed finger slide 42 to drop. This does not take place, however, until the bottom feed finger has moved over the stop 85 which holds the button feed finger in elevated position against the tension of the spring 49. The shoulders 65 and 67 of the upper and lower cam block limit the rearward movement of the cam slide 69. It will thus be seen that as the operating rod 29 is depressed the button feed finger slide is forced forwardly allowing the button feed finger to drop from the stop 85 and engage a button, then carrying the button forward to a position so that the eye thereof may receive the wire B. Arm 83 on the cam 105 then engages the tail of the cam slide to elevate the button feed finger slide and the button feed finger carried thereby so as to release the button, the button feed finger slide 42 mov-' ing rearwardly somewhat with the staple forming slide and upon the upstroke of the operating rod the button feed finger slide is carried rearwardly until the button feed finger engages the stop 85 and the shoulder 79 strikes the pin 77 to start the cam slide rearwardly and allow the button feed fin ger slide 42 to drop to its normal position under the influence of the spring 62;

The coil of wire B from which the staples are formed is kept on the wire holder 90, the wire being disposed in engagement with the under cut shoulders of the feed lever 113 and the bar 124. The pawls 126 and 116 on the bar 124 and the feed lever 113 respectively hold the wire in engagement with the undercut shoulders 125 and 114 respectively and allow the wire to be fed forwardly but prevent any rearward movement of the wire. The staple forming wire B is fed forwardly through passage 142 and through the eye of a button A which has been brought forward is carried by the upper forward end of the cam 100 engages in the notch 109 of the bell crank lever 107 which is pivoted at 108 and swings the same forwardly as shown in Fig. XIII. The other end of the bell crank lever 111 engages the notch 112 in the feed lever 113 and as the bell crank lever is rocked on its pivot the feed lever 113 is caused to rock upon its pivot 115 from the position shown in Fig. II to the position shown in Fig. XIII. It will thus be seen that the wire B which is carried by the feed arm is fed forwardly through the eye of the button which is brought down to receive it as isshown in Fig. XXXIII.

As will be seen most clearl by an inspection of Figs. XXXII to X XVI inclusive, the wire B is fedforward by the wire feedin mechanism through a passage 142 in the bloc 139. The wire cutting knife 134 is slidably mounted in the channel 137 provided in the head block 5 and the tail of the knife has a notch 135 in which a pin 133 carried by the cam 100 is disposed. As the operating rod 29 moves downward the cam99 beingsecured to the cam 33 rocks with the latter on the shaft 35 and the cam surface 99 engages shoulder at the rear end of the notch 135 and returns the wire cutting knife to 1ts normal position.

The parts which form the staple and drive and clench the same and the mechanism for operating these parts are most clearly shown in Figs. XIX to XXII, inclusive. Considering these figures it will be seen that as the operating rod 29 descends it rocks the cam 33 upon the shaft 35 causing the nose 143 of the cam 33 to engage the cam surface 144 of the cam 105, thus rocking said cam upon its pivot 102. This causes the finger 145 at the lower forward edge of the cam to engage the cam surface 146 of the anvil 147 to rock the latter upon its pivot 148. This causes the head 190 of the anvil to approach the staple forming die and the anvil in its rocking movement carries the bracket 153 with the pin 156 inwardly. The pin 156 engages in the slot 157 in the slide 158, and as the anvil is rocked trip slide 158 is moved inwardly. The pin 179 on the bar 162 rests in the notches 160 of the slide 159 so that as the slide 158 is moved rearvvardly it carries the staple forming block with it moving the latter to position shown in Figs. XX and XXXV. As the slide 158 is moved rearwardly through the engagement of the pin 156 in the notch 157 the staple forming block 163 is moved up until it engages the wire which is held in the eye of the button at the end of the staple forming slide 165 and the continued rearward movement of the slide 158 causes the staple forming block 163 to press against the end of the staple forming slide 165 and force the same rearwardly a short distance, the ribs 168 on said staple forming slide sliding in the grooves 169 in the blocks 139 blocks 139 and 170 are so located relative to the top of the block that the wire as it is formed into a staple lies in these grooves as is clearly shown in Figs. XXXV and XXXVI. It will thus be seen that asthe staple forming .block 163 is forced backward carrying with it the staple forming slide 165, the wire held between the block and the end of the slide is bent around the block into the form of a staple by its engagement with the grooves 169 in the blocks 139 and 170. This is clearly shown in Fig. XXXV. When the slide 158 hasmoved rearwardly sufliciently to form the staple, trip shoulder 183 depending from the trip plate 181 into the groove 184 engages the rear end of the said groove to trip the plate on its pivot 182 so as to remove the shoulder at the upper end of the curved slot from beneath the pin 179 on the bar 162. At the same time the end of arm 187 carried bv the cam 105 engages the beveled surface 164 at the rear end of bar 162 and tilts the latter upon its pivot 179 so as to cause the staple forming block 163 to drop below the end of the staple forming slide, as clearly shown in Fig. XXI. The notch 162' is provided in the upper edge of the bar 162 so as to permit the rear end thereof to swing by the rear end of the staple forming slide 165. As the operating rod 29 continues to move downwardly the finger 145 engages the cam surface 189 at the inner end of the anvil so as to rock the same on its. pivot slightly to move and hold it securely in position at the end of the staple forming slide, and, at the same time, the nose 186 of cam 105 comes into engagement with the rear end of the staple forming slide 165 and forces it forwardly pushing the formed staple ahead of it so as to force it through the fabric C and against the clenching late 191 in the anvil head 190 driving the staplethrough the fabric and clenching it securely, as shown in Fig. XXXVI.

As clearly appears, upon the downstroke of the operating rod 29 the anvil is first moved up into proximity to the staple forming block 163, the latter is moi'ed inwardly to engage the end of the staple forming slide gripping the wire which .has been cut off between the end of the slide and the face of the block, the block then moves rear wardly carrying the staple forming slide with it and forming the staple by forcing the ends of the wire against the sides of the grooves 169 in the blocks 139 and 170, respectively. Then when the staple forming slide and block have been moved rearwardly 100 far enough to form the staple, the trip plate is released and the bar 162 is tilted so as to lower the staple forming block 163 and. at the same time, the nose 186 moves forward] against the rear end of the staple 1 5 forming slide 165 forcing the slide and the staple in front of it. driving the staple through the fabric and clenching it against the clenching plate 191.

It will'be seen that after the block en- 11 gagesthe end of the staple forming slide the two are moved rearwardly a short distance. At the same time that this movement takes place, the button feed finger -16 is moved rearwardly a short distance due to the curvature of the upper end of the slot 3 in the arm 40, as has been previously pointed out.

On the upward movement of the operating rod 29 the cam nose 113 engages the 130 cam surface 144 and swings the cam on its pivot 102. This causes the shoulder 152 to engage the shoulder 150 secured to the anvil and rocks the anvil on its pivot away from the end of the staple forming slide carrying the slide 158 forwardly and. at the same time. tilting the bar 162 to its normal position and causing the pin 179 to engage upon the shoulder at the upper end of the slot 180 in the trip plate 181, so that at the end of the upward movement of the operating rod the parts are returned to their normal position as shown in Fig. XIX.

Figs. XXXII to XXXVI show the position of the button A, the wire B and the fabric C at various stages of the operation of the machine. i Fig. XXXII shows them in the starting position. In Fig. XXXIII the wire B has been fed by the wire feeding mechanism through the'eye' of a button A which has been brought down to the end of the staple forming slide by means of the button feeding mechanism. In Fig. XXXIV the knife 134 has moved forward to cut the wire which has been fed into position. In Fig. XXXV the staple forming block 163 has moved rearwardly and forced the staple forming slide and the button carried thereby rearwardly bringing the ends of the wire into engagement with the grooves 169 in the blocks 139 and 170 and forming the staple. In Fig. XXXV the fabric C is shown in position in front of the clenching plate 191 of the anvil head. In Fig. XXXVI the movement is shown completed, the staple forming slide having been forced forward so as to drive the staple through the fabric C and the ends of the staple having been clenched against the curved surface 192 of the plate 191.

Buttons are fed to the machine by the chute 17 5 which extends beneath the block 13 and terminates adjacent the rear end of the staple forming slide 165. This chute is shown in cross section in Fig. XXX and the buttons are arranged therein with the shank or eye depending into the lower portion of the chute. As appears in Figs. XIX and XX toward the lower end of the chute this lower narrowed portion is broken away so that the buttons are supported with the eyes depending beneath the chute. As the buttons come downward, the eyes of the button depend into the channel 17-1 at the top of the staple forming slide 165. A spring 178 is attached to the side of the chute 175 and holds the lowermost button in posi tion untilit is engaged by the button feed finger 4:5 to carry it into position to receive the wire which is fed through it.

In this application we have illustrated and described the operating rod 29 as actuated by the depression of a foot lever 21. It will be apparent, however, that other means of applying power may be used and that any mechanism by means of which a reciprocatory motion. is given to the operating rod 29 may be substituted for the foot lever and the operating parts which we have here shown. We therefore do not Wish to be restricted to the actuation of the operating rod 529 by means of a foot lever as we contemplate the use of any means which imparts a reciprocatory motion to the rod.

We are aware that this particular structure, which we have here shown and described, is susceptible of considerable variation without departing from the spirit of our invention, and, therefore, we do not wish to be restricted to the same. We have found, however, that this particular form is to be preferred, and therefore we desire to claim the same specifically as well as broadly as indicated by our appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
